How to turn off automatic indexes in firestore for subcollection

I don't want to have automatic indexes created by firestore because I need to remove and add every five minutes 50-100 documents (each doc has +/-60 fields) to my subcollection. This causes of big volume for "Cloud Firestore Index Write Ops" (300k / day for only one user) and Cloud Storage. I don't need to sort, filtering that documents so I suppose I can turn off automatic indexes, right?

I know that I can add exemptions for fields, but I don't know how can I use it for documents in subcollections. What should I pass in Collection ID and Field path if the path for documents is like:

mainCollectionName/{id}/subcollectionName/{document=**}

and when should I select a collection checkbox and when collection group checkbox?

Unfortunately, it's not possible to disable indexes or create exemptions for documents to be indexed. As clarified in this similar post here, this cannot be achieved and there is even a limit of 200 exemptions of fields that can be done - you can check the limits here.

For your case, indeed, you would have to exempt the fields individually and besides that, to create the exemption, to set the collection you use its id and not the path. So, you would only need to set in the Collection ID field the subcollectionName and then the field to be exempted.

In addition to this, feel free to raise a Feature Request in Google's Issue Tracker, so they can check about implementing an exemption of documents in the future.
